I don't like playing games of cat and mouse, if I'm not interested then you will know, if I am interested you will know.
I'm also in a relationship with a great guy. I'm on here mostly to find people (preferably female) whom I can get along with and be attracted to both intellectually (first), and hopefully later on to something physically (second). My guy and I would love to have someone for both of us to get along well with--be it as a third or as a couple interested in exploring as well--however if there's a 1:1 interest, I'm perfectly happy with that too.
Finishing up school this last semester while working part-time and keeping a social life balanced. So don't be offended if I can't see you any time soon, just gives us more time to talk and get to know each other.
